Research question To what extent has telemedicine made its way in neurosurgical practice during the COVID-19 pandemic? Material and Methods A 29-question survey was distributed among members of the congress of neurological surgeons regarding (Barsom et al., 2020) the respondents demographics, (Zu et al., 2020) the current level of COVID-19 restrictions, (Greven et al., 2020) the current use of telemedicine and (LoPresti et al., 2020) potential difficulties and consequences of telemedicine for patient care. Results The average number of weekly outpatient visits decreased with 31 visits to a mean of 15 visits per week, while the average number of surgeries performed decreased with 5 to a mean of 2 procedures per week. On average 60% of the normal consultations have been converted to telehealth consults. Telemedicine was expected to increase the ability to quickly meet patients for urgent appointments (70%) but was also expected to decrease the quality of the relationship (56%) between practitioners and patients. The biggest difficulties due to use of telemedicine were the inability to perform physical examination (42%) followed by the inability of patients to use technology (24%) and working with elderly patients (20%).

To what extent has telemedicine made its way in neurosurgical practice during the COVID-19 pandemic?

A 29-question survey was distributed among members of the congress of neurological surgeons regarding (1) the respondents demographics, (2) the current level of COVID-19 restrictions, (3) the current use of telemedicine and (4) potential difficulties and consequences of telemedicine for patient care.

The average number of weekly outpatient visits decreased with 31 visits to a mean of 15 visits per week, while the average number of surgeries performed decreased with 5 to a mean of 2 procedures per week. On average 60% of the normal consultations have been converted to telehealth consults. Telemedicine was expected to increase the ability to quickly meet patients for urgent appointments (70%) but was also expected to decrease the quality of the relationship (56%) between practitioners and patients. The biggest difficulties due to use of telemedicine were the inability to perform physical examination (42%) followed by the inability of patients to use technology (24%) and working with elderly patients (20%).

Telemedicine, however, comes with concerns regarding the quality of the relationship between patients and practitioners and regarding accessibility among certain patient groups. With these concerns, areas of improvement and further research are indicated. Due to the COVID-19 pandemic, telemedicine has become an integral part of the neurosurgical healthcare.

Neurosurgery; Telemedicine; COVID-19 J o u r n a l P r e -p r o o f Introduction:

Within a few weeks the corona virus disease 2019 (COVID- 19) pandemic demanded a quick adaptation of many medical specialties (1) . To maintain sufficient physical distance and to downscale on resources, change was not only visible in the different approach that was needed to provide health care services, but also in the way education was continued during the pandemic (1) (2) (3) (4) (5) . Telemedicine is a way to provide health care services at a distant, using various ways of technology for exchanging valid information that is medically related (6) . Apart from being a necessity, this change can also be an opportunity to evaluate the usage of telemedicine in the medical field of neurosurgery. The use of telemedicine itself, however, is not a new concept in Neurosurgery. For instance, previous research on the applicability of telemedicine Neurosurgery has shown that telemedicine leads to faster diagnosis of stroke, which may lead to improved patient outcomes due to increased applicability of tissue plasminogen activator(7-10).

Even though due to COVID-19 the shift towards the use of telemedicine was a necessary step, the use of telemedicine in general has many advantages for patients and practitioners. For instance due to decrease costs by saving time and nullifying mileage(11), reducing waiting time for referrals (12) and even higher patient satisfaction and better patient care (13, 14) . Other observations were a positive effect on decision-making(11), increased accessibility and participation to meeting, conferences, multidisciplinary patient discussions and educational sessions (5, 10, 13) . Telemedicine also created new initiatives such as student telehealth hotspotting to provide wellness calls for patients with e.g., higher risk of social isolation (15, 16) .

Aside from these advantages, telemedicine may also pose some disadvantages such as difficulties to perform physical examination (15, 17) . Other disadvantages may be difficulties to establish an emotional connection with patients on distance or disparity in access to medical care due to the requirement of a computer and broadband internet connection to use telemedicine (15, 18, 19) . Furthermore, the use of internet and computers may also be difficult for older patients which may also negatively influence their access to telemedicine (20) .

The advantages together with the increased implementation of telemedicine due to COVID-19, may lead to a more permanent place of telemedicine in the medical world even after the pandemic. These prospects emphasize the need to assess and optimize the use of telemedicine to further implement the technology responsibly (13) . Preliminary data suggest that geographical variation in the use of telemedicine and some shortcomings of telemedicine among neurosurgeons worldwide(21). By the means of this full report of an international survey, we aim J o u r n a l P r e -p r o o f to give an overview of the use of telemedicine due to COVID-19, the difficulties encountered with the use of telemedicine and the consequences of the use of telemedicine for patient care.

J o u r n a l P r e -p r o o f Methods Based on the literature a 29-question survey was created (4, 22, 23) . The survey consisted of four parts: (1) demographics of the respondents; (2) the current level of COVID-19 related restrictions; (3) the use of telemedicine and (4) the (potential) difficulties and consequences of telemedicine for patient care. The demographics-section contained questions about the function and specialty, years of clinical experiences, country of employment, age, gender, the average number of outpatient visits per week and the average number of surgical procedures per week before the start of the pandemic. The second part contained questions on the average number of outpatient visits and surgical procedures per week during the COVID-19 pandemic. Additional questions were asked on the level of COVID-19-related restrictions at their institution, and the level of involvement in regular and COVID-19 related patient care. The third section contained questions regarding remote access to medical records, laboratory and radiology data and if patients are currently council using telemedicine. The fourth path contained three questions on how respondents thought the increased use of telemedicine affects patients, themselves and their practice. Furthermore, respondents were asked to comment on the difficulties encountered with telemedicine and to estimate the influence of telemedicine on different aspects of the quality of the care given.

The survey was distributed among the members of the Congress of Neurological Surgeons using SuveryMonkey (Palo Alto, California, USA). The survey was distributed on May 3, 2020, followed by two-weekly reminders till July 2020. The Statistical Package for Social Sciences, version 21.0 for Windows (SPSS, Inc.) was used to analyze the generated data of the survey. The data descriptive statistics were used to present the available data and to display the available data, valid percentages were used. Statistical significance was set at 0.05.

A total of 363 out of the 5625 approached members replied leading to a response rate of 6.5%. Respondents were employed in a total of forty-three countries with most of the respondents being based in the U.S.A. (see figure 1 ). Most respondents were either neurosurgeon (94.2%) or neurosurgical resident (5.2%), while 11.6% of the respondents overall were female (see table 1 ). Before the COVID-19 crisis, respondents had an average of 44.5 ± 53 outpatient visits per week, while performing an average of 6.8 ± 5.1 surgical procedures weekly.

During the COVID-19 crisis, the average number of outpatient visits per week decreased to 14.7 ± 14.4 (mean difference -30.7, 95% CI -36.2 to -25.2) while the average number of surgeries performed decreased to 2.3 ± 2.3 (mean difference -4.6, 95% CI -5.1 to -4.1) per week (see table  2 ). For most respondents (59.7%), all non-essential visits and procedures needed to be postponed while 9.0% of the respondents had experienced no COVID-related restrictions. Furthermore, 21.7% of the respondents were requested to perform guard duties on the ICU, ER or Inter Medicine ward. Overall, 85.1% was still able to physically see patients or to perform surgery. Of current patient group consultations, the majority of 47.7% consisted of emergencies and 40.2% consisted of suspected high-grade neuro-oncology. Overall, only 2.4% of the respondents was not performing surgery at all. Of the neurosurgeons that did perform surgery, 33.6% performed surgery for neuro-oncology, 24.1% performed only trauma surgery and 23.8% for degenerative spinal surgery.

Overall, 87.6% of the respondents had remote access to patient data and used telemedicine for consultations. Telemedicine was mostly used for consultations of known and new patients (56.2%) and in lesser extent for only known patients (47.1%), lectures (32.8%), research meetings (27.5%), peer consultations (22.9%) and emergencies (14.9%). Telemedicine was applied by the means of telephonic consults (52.6%), video consultations (58.1%) and Email/WhatsApp/other social media applications (22.6%). For almost all respondents (96.7%) the use of telemedicine has increased during the pandemic. On average, 59.7% of the normal consultations have been converted to telehealth consults. Overall, 76.2% of the patients are receptive to telemedicine, 16.2% is neutral and 5.1% is not receptive.

Difficulties experienced using telemedicine and consequences of telemedicine on patient care Figure 2 gives an overview of the difficulties neurosurgeons encounter during the usage of telemedicine. The biggest difficulty experienced with telemedicine is the limited capability to perform physical examination (by 41.9%). This was followed by the inability of patients to use technology (24.1%) and working with elderly patients (20.2%). Smaller difficulties were experienced with privacy concerns and financial aspects, while most neurosurgeons (55.4%) were neutral regarding difficulties due to malpractice liabilities.

Respondents' opinion on the consequences of telemedicine application on different aspects of patient care are depicted in figure 3 . Overall, the majority (69.8%) expected an increase in the ability to quickly meet patients for urgent appointments. However, majorities also expected declines in the quality of the relationship between practitioners and new patients (55.8%) and the quality of interaction between practitioners and patients (50.7%). For returning patients, the majority (55.4%) believed that the use of telemedicine would not influence the quality of the relationship. Overall, respondents were more divided on the effect of telemedicine on the quality of care in general. Table 4 gives an overview of a selection of open answers on how the increased use of telemedicine has affected patients and surgeons themselves together with their practice.

J o u r n a l P r e -p r o o f

The current study presents the results from a survey among 363 members of the CNS regarding the use of telemedicine, the difficulties experienced with the use of telemedicine and the consequences of telemedicine application on patient care. At the time of answering the survey, the average number of weekly outpatient visits decreased with 31 visits to a mean of 15 visits per week, while the average number of surgeries performed decreased with 5 to a mean of 2 procedures per week. Overall, 85% of the respondents were still able to physically see patients or to perform surgery. On average 60% of the normal consultations have been converted to telehealth consults. Most used forms of telemedicine were video consultations and consultations by telephone. From the perspective of the neurosurgeon, 76% of the patients were receptive to telemedicine. Telemedicine was expected to increase the ability to quickly meet patients for urgent appointments but was also expected to decrease the quality of the relationship (56%) between practitioners and patients. The biggest difficulties faced with the use of telemedicine were the limited capability to perform physical examination, followed by the inability of patients to use technology and working with elderly patients.

As the use of telemedicine has increased massively during the COVID-19 pandemic, so has the research on the use of telemedicine (24) (25) (26) (27) (28) (29) (30) (31) . Table 5 gives an overview of eight published survey results on the use of telemedicine during the COVID-19 pandemic among neurological and spine surgeons. Most of these studies were conducted during summer 2020 among mostly members of professional organizations. In general, these studies conclude that surgeons are receptive of telemedicine to perform consultations but that some concerns remain such as patients` preferences for in-person visits, the limited capabilities to perform physical examination and technical issues. These findings are in line with our current study.

In the literature multiple recommendations are published on how to improve quality and how to improve the acceptance of telemedicine among both patients and health care providers (4, (32) (33) (34) . In a well-written review paper by LoPresti et all, seven common problems with solutions were discussed on how to effectively apply telemedicine. These problems involve:

1. Patient access: elder patients or patients with language barriers may find more difficulties in using telemedicine or effectively communicating symptoms. This can be solved by having a helpdesk or by using the telephone while treating patients that are not able to set-up the proper telemedicine necessities. 2. Provider access: this can be solved by having the correct equipment, rooms and software available to providers.

3. Limitations in performing physical/neurological examination: although it is not feasible to perform all parts of the physical examination through telemedicine, initiatives have been taken to implement standardized remote physical examinations(35). 4. Privacy/confidentiality concerns: providing patients information on patient confidentiality is key in this. 5. Potential issues with billing: billing issues may be very dependent on the health care system of the provider, but since the start of the pandemic many issues regarding billing of telemedicine services may have been solved. 6. Malpractice liabilities: health care providers should make sure that if they cannot make adequate decisions in managing patients through telemedicine, that in-person visits should be considered. 7. Restrictions due to medical licensure: this may be very dependent on the location of the health care provider.

In the current study, most of the patients are receptive to telemedicine from the perspective of the neurosurgeons. However, neurosurgeons also expected that the application of telemedicine had a negative effect on the quality of interaction between patient and practitioner and a negative effect on the quality of the relationship between practitioners and new patients. In this study the patients` perspective was not evaluated. This belonged, however, to the scope of other studies (36) (37) (38) . In their retrospective analysis of survey data of 97 patients that were consulted by telemedicine and 589 patients who had in-person consultations, Porche et al. showed that overall patient satisfaction did not differ between both patient groups (36) . Satisfaction scores on other domains such as accessibility to care and contact with the care provider also did not differ between both patient groups. In a survey among 176 patients at a spine clinic, Maurer et al. showed that patients that who had to travel further distances to the hospital may be associated with favoring telehealth and that most spine patients preferred in-person appointments over virtual appointments 34 . However, in a larger prospective analysis of 310 patients that underwent a telemedicine visit in a U.S. based Neurosurgery department, Yoon et al. measured satisfaction with telemedicine with questionnaires distributed after their consultation (37) . On a scale of ranging from 1 to 7 (= very satisfied), the average score was 6.3. Of all the telemedicine consultations, only 1 patient (0.3%) was sent to the emergency department and 94 patients (30.3%) had imaging ordered, indicating that most of the patients could be successfully consulted by telemedicine only. Additional analyses of satisfaction scores among patients who lived at more than 15 miles distance to the hospital versus those who don't, and between returning and new patients, revealed no differences. The prior contrasting with the expectation of neurosurgeons in our current survey.

Some limitations must be acknowledged such as the response rate. Even though our response may be somewhat comparable to other surveys conducted among large physician databases such as AOSpine International, the response rate can be rated to be low. A low response rate may induce selection bias, but as the survey did not cover controversial topics, it is not to be expected that specific group of surgeons will be more motivated to reply. As table 5 shows, quite a few surveys were conducted during the summer 2020 and this might have negatively impacted the response rate. Nevertheless, the absolute number of respondents is high enough to give an impression on the application of telemedicine during the COVID-19 pandemic. Furthermore, the survey response rate might not necessarily be related to the quality of the study (39) . Other limitations inherent to the study design, e.g. recall bias, also warrant cautious interpretation.

Due to the COVID-19 pandemic, telemedicine has become an integral part of the neurosurgical healthcare. Telemedicine, however, comes with concerns regarding the quality of the relationship between patients and practitioners and regarding accessibility among certain patient groups. With these concerns, areas of improvement and further research are indicated. Figure 2 : Difficulties encountered during the practice of telemedicine.

Overview of selected open answers on questions regarding how the increased usage of telemedicine has affected (1) patients and (2) themselves and their practice. J o u r n a l P r e -p r o o f J o u r n a l P r e -p r o o f How do you think these changes affect your patients? "Decreased accuracy of detailed physical exams, but improved access for many patients that travel long distances." "This is a positive change. My patients are no longer required to come to the office and I am able to see new consultations by video consultation. This has decreased the amount of travel my patients are responsible for." "Delays in management and delays in presentation to the hospital for some emergencies." "Easier access for patients. Difficult to show imaging studies to patients. Not able to perform a neurological exam." "For patients traveling a great distance or who are in medically poor areas of the US, allows better and more timely access and evaluation by neurosurgery." "I think it's stressful. Some patients have shown up for their telemedicine visit while driving a car with the child not in the car and it was the child's visit. Somethings are very hard to see and examine, particularly in infants. Well somethings lend themselves well to telemedicine, I remain extremely concerned that other things do not, and that people are too scared to come in, and that we are not able to do a good job and evaluating them over a camera."

How do you think these changes affect you and your practice? "This has had a positive impact. Based on insurance restrictions I cannot order imaging without seeing a patient which results in 2 trips to the office. Now, I am able to see the patient in consultation over video visit and then order the imaging. Then the patient is able to come to clinic the same day as imaging is done or go home and follow up over video visit." "Mixed: lack of graded motor and reflex exam is limiting, but, by same token, being able to still provide care to people despite strict precautions is good." "I will continue telemedicine for post ops, follow ups (image review), and patients who live farther away. I will use this as a screening appointment to assess need for in-office exam and need for further imaging/management before offering surgery." "Increased time required to coordinate outpatient communication, improved efficiency and access to patients for clinic." "It is extremely time consuming. It takes twice as long to do a telemedicine visit as it does an in person visit, and then there is the backtracking to check on x-rays and labs which need to be performed at other places, and then need to be called back and discussed. Patients have much more limited access to viewing their images unless I hold my computer up to another computers' camera."
